That comment must be about a set up the user encountered that gave him that impression but it is an incorrect statement. There is no 100 vs 150 being different in any way other than max SPL and low frequency roll off. The models are identical except for a 15 inch LF driver and big box vs. a 12 inch LF driver and smaller box. The mid has its own enclosure as does the tweeter so no effect on either by the box size. They also share the same 3 channel amp pack so no amp differences.

Thrill is right, I think the 150 is the best sounding PRO speaker ATC makes.
